Not understanding Boot Environments
-
Hello,
yesterday, I felt the urgent need, to update to the current 25.07 RC.
A boot environment snapshot was taken automatically.
Upgrade worked fine and after reboot, the 25.07 RC was working fine - including all updated packages.
However, when I later attempted a rollback, I went to Boot Environment and selected via the "play button" the old snapshot.
It rebooted to 24.11 but the packages seemed to be still the packages from 25.07. It was a hassle to downgrade them again to 24.11 status. It seems that the selected upgrade branch was still selected to 25.07.
What should be part of a snapshot?- Full OS?
- Full config?
- Full packages?
- Selected upgrade branch?
- ...?
Thanks in advance for any insights – much appreciated!

Even if, you select the right branch and are good, nothing else to do or downgrade.
I too think it is not as easy to get, what it is doing but once you learned about snapshots and the package system in pfSense, there is no problem. -
@renegade reverting should not need to reinstall packages so not sure what happened. A BE is basically “stop writing to ‘this disk’ and start another.” Loosely.
The (>) button is one reboot: https://docs.netgate.com/pfsense/en/latest/backup/zfsbe/gui.html#selecting-boot-environments-in-the-gui
